WebSolution: An arithmetic progression (AP) is a sequence where the two consecutive terms have the same common difference. It is obtained by adding the same fixed number to its previous term. From the question: a = -5 d = 2. The formula to find the sum is Sn = n/2 [2a + (n - 1)d]. Substituting the values, we get, S₆ = 6/2 [2a + (6 - 1)d] Webn th term of an AP is T n =a+(n−1)d For an AP with the first term as 'a' and common difference as 'd', the seventh term is a + 6d.
